Donor–acceptor π-conjugated polymers based on terthiophene-3,4-dicarboxylate, dithienopyrrolobenzothiadiazole and thieno3,4-cpyrrole-4,6-dione units and their hole mobility

We have synthesized three different p-type donor–acceptor π-conjugated polymers based on diethyl 2,2′:5′,2′′-terthiophene-3′,4′-dicarboxylate, dithienopyrrolobenzothiadiazole and thieno3,4- c pyrrole-4,6-dione units.
